Abstract

|
|
Background/Aims: The Compliance Questionnaire-Rheumatology (CQR) is a validated scale to evaluate patient
compliance for anti-rheumatic medications. We developed a Korean version of the CQR (KCQR) and confirmed its reliability and validity.
Methods: We prepared the KCQR by translating and back-translating the original CQR with modifications to adapt it to Korean culture. Fifty Korean patients with rheumatoid arthritis (RA) were enrolled in this study. The test-retest reliability of the KCQR was evaluated at a 2-week interval using the intraclass correlation coefficient (ICC). The validity of the KCQR was assessed by identifying associations between KCQR scores and patient compliance, measured using pharmacy refill data.
Results: The reliability of the KCQR was adequate, with an ICC of 0.71 for test-retest reliability. With respect to
validity, the summed score of the weighted KCQR showed a significant correlation with pharmacy refill data (r2 = 0.57) on multiple regression analysis.
Conclusions: Our results indicate that the KCQR is a reliable, valid instrument to evaluate compliance of Korean
patients for RA medications.
